Naming Notes
Molecular or Covalent CompoundsMolecular or Covalent Compounds have specific properties:
- They are between at least 2 non metals. - They share electrons - Usually have low melting and low boiling points - Tend to be soft - Not very good conductors Ionic Compounds

Ionic compounds have specific properties:
- They are between a metal and a non metal.
- They transfer electrons
- The charges of the ions must balance (Na ion has a charge of 1+, Cl ion has a charge of 1-. Therefore the formula is NaCl)
- Have high melting and high boiling points
- Conductive when liquid
- Usually soluble

What we know about the Periodic Table
Atomic Number: the number of electrons, the number of protons
Atomic Mass: The mass of the atom Neutrons: To find the number of neutrons, you subtract the number of protons from the atomic mass and round to the nearest whole number. Groups= columns in the periodic table Periods= rows in the periodic table Group 1 is known as the Alkali Metals
